Well, I develop a web browser called "Telecom". Instead of using a tabbed browser control, I use multiple forms for tab switching, and most of the tab switches look like

I have an mdi form where the child forms need to maintain aspect ratio in normal state and have resize procedures that work well except with one form that appears to have a bug.
This form is the first child form opened, it is set as maximised in design and looks ok. If I then open another form on top, this maximised form, with a size of 1920x942, goes through my control resize code insisting it is in normal state and has a size of 1428x822. Obviously, when I close the other form the controls are wrongly resized/positioned.
I thought I might check the eventargs to test if the controlbox has actually been used and ignore otherwise but debug always reports that as empty. Lostfocus, deactivate etc don't trigger before resize so can't set a flag there.
why just this one form appears to be insane, or how I can distinguish between an intended resize and one just due to hiding by another form?
Has anyone had any luck with having different window states with multiple open child forms?for example if you have a single child form opened and say it is maximized.then open a second child form as normal, the first form will then be set to normal.all the open child forms will mimic the newly opened forms state.and i believe they will mimic when making some changes to one forms state.the others will follow.i have not had luck keeping this from happening in most situations.

View 3 RepliesI have a dual monitor setup on my computer. My program has multiple forms. I've designed the program to check which monitor the main form is currently on and to open the secondary forms on the current monitor. When the main form is on the primary monitor the secondary forms open as FormWindowState.Normal which is the design-time setting for the secondary forms. If the main form is on the secondary monitor and I click to open a secondary form then the secondary form is to be displayed as FormWindowState.Maximised.
[Code]...
So I moved the Form.Show line to after the Form.WindowState line. This works fine when the Form.Show process is very quick. The problem is that one of the secondary forms downloads some information from the internet so it takes about a second to finish the Form_Load process. When I had Form.Show first the form would not appear on screen until the Form_Load process is complete, so the delay was in the form appearing at all which is how I prefer it. With Form.Show last the form appears on screen immediately but appears mostly blank and unresponsive until the Form_Load process completes.
I would prefer that the form not appear at all until the Form_Load process is complete but I would like it to appear in an already Maximised state. Is this achieveable? It doesn't seem that complicated but I just can't figure it out.
Below is a short section of code from an application I am working on. What I am trying to do is to get a counter value to show when the application is minimized. When restored back to normal state, the name string is applied. It works, but it takes several minutes to change, and then never updates again. Not sure what the issue is.
[Code]...
I also tried a direct string conversion in the "elseif" part. No difference.
I need to store the Location, Size and WindowState of my application when it is closed, so that it can be re-opened in the same state later. I thought I could use simple coding and the Settings to achieve this, but I noticed the PropertyBinding of the Form in a tutorial and decided to see if I could use it.

View 3 RepliesI have 2 listbox's, same locations/sizes (one behind the other). I have 2 buttons, and they just switch the views between the listbox's by changing their visibility propertyThe problem is listbox1, which gets populated first, displays just fine. No code in the program touches listbox2, except for 1 button that adds items. When switching to listbox2 to see the added items, the items are there (verified by debugging and hovering over the added variable), but the text that is displayed won't update. The text that is displayed is the text from listbox1.

I have an application I wrote that is in VB.NET 2.0. Works great, but I'd like to switch this application to Linq. I use ADO.NET to load XML into a datatable. The XML file has about 90,000 records in it. I then use the Datatable.Select to perform searches against that Datatable. The search control is a free form textbox. So if the user types in terms it searches instantly. Any further terms that are typed in continue to restrict the results. So you can type in Bob, or type in Bob Barker. Or type in Bob Barker Price is Right. The more criteria typed in the more narrowed your result. I bind the results to a gridview.
1) Go to Project Properties --> Advanced Compiler Settings and change the Target framework to 3.5 from 2.0.
2) Add the reference to System.XML.Linq, Add the Imports statement to the classes.
So I'm not sure what the best approach is going forward after that. I assume I use XDocument.Load, then my search subroutine runs against the XDocument. Do I just do the standard Linq query for this sort of repeated search? Like so:
Dim people =
from phonebook in doc.Root.Elements("phonebook")
where phonebook.Element("userid") = "whatever"
select phonebook
